永磁同步电机直接转矩控制的综述

Overview of Permanent Magnetic Synchronous Motor Direct Torque Control

在高性能伺服系统中,使用直接转矩控制的永磁同步电机来实现对电磁转矩的快速和精确控制,针对永磁同步电机直接转矩控制介绍了相关的电力电子变换器,并综述了研究领域中的低速转矩脉动、定子磁链的观察以及无速度传感器技术。

In high performance servo system, the direct torque control of permanent magnetic synchronous motor was used to real- ize fast and accurate control of magnetic rotation torque. Aiming at the direct torque control of permanent magnetic synchronous mo- tor, this paper introduced the relevant power electronic converter and described low speed rotation torque ripple, observation of stator flux and non-speed sensor technology.
